Working Petscans frequently return a 502 Bad Gateway error.
Examples I use regularly, and which frequently enough return a 502, are:
From the user pov, there doesn't seem to be any rhyme or reason. Sometime the petscan works. Sometimes a 502 is returned.
- What is the cause of these 502s?
- Can the underlying problem be fixed, please?
- If the problem cannot be fixed, can we have a more informative error message - e.g. if there's a query timeout, could we be informed of this?
